Abstract Total chromogen, true, and AutoAnalyzer methods of measuring serum and urine creatinine by the Jaffe reaction were investigated. Some factors influencing this reaction were examined. These included wavelength, blank, linearity, and conditions of color development. Modifications of the three methods were made and their precision, recovery, and sample stability determined. The interference of ketones and glucose were measured. Finally, the values obtained by the three methods on the same samples of serum and urine were compared statistically.

A new, totally enzymatic procedure for the determination of creatinine in serum and urine, using creatinine amidohydrolase, creatine amidinohydrolase, sarcosine oxidase and formaldehyde dehydrogenase is described. The assay was adapted to a discontinuous analyser with each analysis requiring only 20 μL of serum or 3 μL of urine. Analytical recovery of creatinine in serum and urine averaged 100·6%. Within-run and between-run precision studies gave coefficients of variation of 1·1% and 1·8%, respectively, for a serum with mean values of 83 μmol/L (9·4 mg/L) creatinine. Creatinine concentrations in serum and urine were measured by this procedure, in Japanese children and adults. The reference intervals for serum creatinine concentrations in adults were 55–96 μmol/L (6·2–10·9 mg/L) in men and 40–66 μmol/L (4·5–7·5 mg/L) in women, and for urine, 9·46–19·01 mmol/day (1070–2150 mg/day) in men and 6·75–10·61 mmol/day (764–1200 mg/day) in women. The reference intervals of creatinine clearance were 88·0–176·4 mL/min in men and 75·7–173·0 mL/min in women.

Study from the Environmental Office of Yogyakarta, indicates in Kotagede found the pollution of mercury from the environment because of improper disposal of wastewater. This study aims to assess the levels of mercury, creatinine and urea in the serum and urine of people working in several industries in Kotagede and Banguntapan. Subjects of this study were 52 employees in several industries in Kotagede Yogyakarta with a range of ages between 20 - 71 years and length of work between 3 - 38 years. A total of 42 people with the age range was 21 - 63 years and the length of work between 1 - 20 years were taken from industrial employees in Bantul who have almost the same geographical conditions as Kotagede. Determination of mercury levels using the Atomic Absorption Spectrophotometry (AAS) method while the determination of urea and creatinine levels by a Dyasis kit. In Kotagede, there were 3 people (5.8%) with the average mercury serum of 0.217 ppb and no mercury in the urine was found in all subjects. In Banguntapan, one person (2.4%) had 0.200 ppb mercury serum and 6 people (14.3%) had an average mercury urine level of 0.395 ppb. Urine creatinine and urea levels in subjects from Kotagede were higher than those from Banguntapan (p<0.05), despite being on the normal range. The presence of mercury in several industrial employees in Kotagede and Banguntapan is still on the low range even though it was correlated to creatinine levels.

Abstract. Residual insulin secretion, reflected by the presence of C-peptide in serum and urine, has been demonstrated in 5 of 10 insulin-requiring diabetics of less than 10 years' duration tested. The C-peptide response, in the C-peptide secretors, showed a significant increase in both serum and urine after 4 weeks' treatment with 15 mg glibenclamide daily in addition to their usual insulin regime although no beneficial effects in metabolic control were detected. It is suggested that glibenclamide might be a useful adjunct to insulin therapy in insulinrequiring diabetics who still secrete C-peptide.
